repos/redhat: install yum-plugin-priorities

yum-plugin-priorities package is needed when running RDO trunk
packaging, repositories have priorities and we need to address them.

This patch adds a boolean: $manage_priorities, set to True by default.
If set to False, yum-plugin-priorities package won't be installed by
this module.
